Brand Development Index

From Wikipedia, the free encyclopedia

Brand Development Index or (BDI) measures the relative sales strength of a brand within a specific market (e.g. Pepsi brand in 10 - 50 year old's). It is a measure of the relative sales strength of a given brand in a specific market area.

[edit] Calculate

BDI is calculated by:

(A% / X%) * 100

where A is the percentage of a brand's total sales in a specific market area, and X is the percentage of the total population in that market area.[1]

[edit] Uses

The BDI is especially useful in conjunction with the Category Development Index (CDI). It can be used in deciding the allocations in the media to which a specific brand is advertised. It can also be used to determine how much advertising, or promotion effort is, or should be put in that specific market.
